SPECIFICATION forming part of Letters Patent No. 442,395, dated December9, 1890.

Application filed March 24, 1890- Serial No. 345,096- (No model.)

To all whom, it may concern.-

Be it known that I, ALvIN LINUS Rmco, of Chicago, Cook county, Illinois,have invented certain new and usefulImprovements in Sarnple-Books, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon.

Herctofore in the manufacture of samplebooks it has been customary toplace the inner edge of each collection or group of leaves between thefolds of several thick paper stubs and then sew the same to a strip ofcanvas or othersnitable material before completing the book by puttingon the covers and back. This construction makes it necessary to dependentirely upon the thickness of the stubs for space between the leaves,and, when the book is designed for the display of very thick materials,makes the cost of material. and labor of putting it together a veryconsiderable item.

The object of my invention is to provide a very simple and effectiveconstruction for the back of a sample-book, in which, no matter whetherfor the display of thin or heavy goods, the space for the leaves can beeasily gaged and maintained without the use of additional materialintervening between the inner edges or bends of each collection or groupthereof, substantially as hereinafter fully described, and asillustrated in the drawings, in which- Figure l is a view looking at thebottom edge of my improved book. Fig. 2 is a perspective view of acorrugated strip used in the construction of the back. Fig. 3 is across-section through a group of the several parts relatively arrangedbut disconnected. Fig. tis a view of the back of my book with the outercovering of the same removed; and Fig. 5 is a cross-section similar toFig. 3, showing said parts connected.

Referring to the drawings, A A represent groups of leaves, each groupmade, preferably,by taking several sheets of paper of a length twice thedistance that it is intended the width of the leaves shall be and. thenfolding it so as to give it the bend a.

B represents a strip of paper or other suitable material of a widthcorresponding to the width of the back and of a length corresponding tothe height of the book. This strip B is provided with lengthwisecorrugations, and

is curved laterally slightly, so as to conform to the curvature of theback of said book. To the back of strip B, I paste a strip C, of plainpaper, of about the same weight as strip B, and then back strip C with apiece of board I), made of straw, cloth, leather, or wood fiber. To theback of board D, I paste a piece of canvas or leather Z) to make what isknown as a flexible back. I then take each group of leaves and place thebend a thereof in the valley between each, or, if desired, everyalternate corrugation, and by means of thread or wire stitches sew thesame thereto. \Vhen this is done, all that remains to do is to attachthe exterior back and covers c of the book in the usual manner.

\Vhat I claim is- 1. In a sample-book, the combination of the groups ofleaves A with the corrugated strip B, between the corrugations of whichand to the rear bend thereof said leaves are secured, and the back andcover of said book, as set forth.

2. In a sample-book, the combination, with the groups of leaves A, ofthe corrugated strip 13, between the corrugations of which and to therear bend thereof said leaves are secured, board D, and theba-ck andcover ofsaidbook, as set forth.

In a sample-book, the combination, with the groups of leaves A, of thecorrugated strip B, between the corrugations of which and to the rearbend thereof said leaves are secured, strip C, pasted to the backthereof, and the back and cover of said book, as set forth.

l. In a sample-book, the combination, with the groups of leaves A, ofthe corrugated strip B, between the corrugations of which and to therear bend thereof said leaves are secured, strip C, pasted to the backthereof, board D, and the back and cover of said book, as set forth.

5. In a samplabook, the combinatiolnwith the groups of leaves A, of thecorrugated strip B, between the corrugations of which and to the rearbend thereof said leaves are secured, strip C, pasted to the backthereof, board D, piece of flexible material I), and the back and coverof said book, as set forth.
